GENERAL DESCRIPTION
The ADN3010-11 is a high speed optical receiver featuring a
proprietary large area germanium photodiode monolithically
integrated with a silicon TIA and LA. The integration of the
photodiode eliminates bond wires between the diode and the
TIA that provides guaranteed performance and improved
manufacturing reliability. The 50 μm diameter photodetector
enables an easy optical coupling design when aligned with a
single mode fiber (SMF). With a 1310 nm optimized ARC, the
ADN3010-11 supports 10GBASE-LR and other applications
with extended data rates of up to 11.3 Gbps.
Although the ADN3010-11 can operate in the wavelength range
from 850 nm to 1565 nm, it has an antireflective coating (ARC)
centered at 1310 nm and is characterized only at original band
Rev. 0
(O band) wavelengths (1270 nm, 1290 nm, 1300 nm, 1310 nm,
and 1330 nm) in this data sheet.
The power monitor pin provides either an output voltage or
current that is proportional to the sensed average photocurrent.
Typical power consumption of the ADN3010-11 is 102 mW
from a single 3.3 V supply. When the output is saturated, it has
a typical differential amplitude of 460 mV p-p at 10.52 Gbps.
The ADN3010-11 is available in die form, and it is operational
over the extended industrial temperature range of −40°C to
+85°C.

THEORY OF OPERATION
The power monitor pin, PM, provides either a voltage or a
current output that is proportional to the sensed average
photocurrent. This feature allows the user to check how
well a fiber or an optical coupling system is aligned to the
ADN3010-11 photodetector (PD), which is typically useful
during receiver optical subassembly (ROSA) manufacturing.
best fit straight line allows extrapolation of the OMA sensitivities at either BER = 10−10 or 10−12 from the measured OMA
input data at a wider range of BER. The extrapolated BER =
10−10 sensitivity spans from −16.8 dBm to −17.4 dBm OMA and
the BER = 10−12 sensitivity spans from −16.4 dBm to −16.8 dBm
OMA at various temperature and supply voltages.
To receive a PM pin signal from a transistor outline (TO)
packaged ROSA, the TO header must support at least five pins.
Figure 6 shows the ADN3010-11 supply current, ICC, vs. optical
average power, PAVE, at various temperatures and supply
voltages.
Figure 3 shows BER at 10.52 Gbps vs. input OMA at various
temperatures and supplies. In Figure 3, fitting the curve to a

The PMO offset is composed of the ADN3010-11 photodiode
dark current (mirrored) and a preset offset current (see Table 1
for details).
POWER MONITOR OUTPUT ESTIMATION
The PMO can be used to achieve optimal optical coupling. To
use the PM pin properly, calibrate the integrated PD dark
current out because the dark current is temperature and
reversed bias dependent.

In voltage mode,
PMO = (VOC – VDK)/0.7/PAVE (optical power)
In current mode,
PMO = (ISC – IDK)/0.7/PAVE (optical power)
Bonding this pad is not necessary in a metal header package [TO].
POWER MONITOR (PM) OUTPUT APPLICATIONS
The PM output can be set in either voltage output mode or
current output mode for a mirrored photodidode current, IPD,
which includes sensed photocurrent plus a preset offset current.
Therefore, IPD is proportional to the sensed photodiode current.
The setup of the VOC (open circuit voltage output) and ISC (short
circuit current output) measurement is shown in Figure 10.
where:
PMO is the power monitor output (A/W) in voltage and current
modes.
VOC is the voltage output (mV) produced by an input light with
an optical average power, PAVE.
VDK is the voltage output (mV) at no light input, PAVE = 0 mW.
PAVE is the average optical power of an input light to the receiver
PD.
ISC is the current output at an input light with PAVE = 100 mW.
IDK is the current output (µA) at no light input, PAVE = 0 mW.
